Definitions
- the present invention relates to the field of communications, and in particular, to a terminal access method and terminal.
- a code division multiple access (CDMA) communication system protocol specifies that an access slot is composed of an access message prefix length (PAM SZ ) and an access message body length (MAX CAP SZ ), where parameters The MAX CAP SZ and the parameter PAM SZ are sent by the base station to the terminal through the air interface message.
- the structure of the access slot is shown in Figure 1.
- the length of the access slot is (1+PAM_SZ) and (3+MAX_CAP_SZ).
- the sum value, the unit of the sum value is the frame.
- the access slot is represented in time as the product of the length of the access slot and 20 milliseconds (ms).
- the length of time for the terminal to access the CDMA system is mainly determined by the access slot.
- the procedure for the terminal to access the CDMA system is as follows:
- the terminal determines whether the access time slot is aligned. If yes, perform 102.
- the terminal sends an access message prefix, that is, the terminal sends an access message prefix to the base station after the access time slot is aligned.
- the terminal sends an access message body. After the access message prefix is sent, the terminal constructs an access message body according to the configured parameter MAX_CAP_SZ value, and sends the constructed access message body to the base station.
- the access time slot is caused. As the size becomes larger, the number of terminal accesses per unit time becomes smaller, thereby causing waste of the access channel.
- the technical problem to be solved by the present invention is to provide a method and a terminal for accessing a terminal, which can solve the problem of waste of an access channel caused by an increase in an access slot in the prior art.
- the present invention provides a method and a terminal for accessing a terminal, and the technical method is as follows: A method for accessing a terminal, comprising: calculating a length of an access message body of an access message; The length of the access message prefix and the length of the access message body construct an access slot; when the access slot is aligned, the access message prefix is sent to the base station; and the access message body is sent to the base station.
- a terminal comprising: a calculation module, configured to calculate a length of an access message body of an access message; and a constructing module, configured to construct an access according to a length of the configured access message prefix and a length of the access message body a first sending module, configured to send an access message prefix to the base station when the access time slot is aligned; and a second sending module, configured to send an access message body to the base station.
- the technical solution provided by the present invention constructs an access message body by calculating the length of the access message body of the access message in real time, and replaces the length of the uniformly configured access message body with the calculated length of the access message body, and sends the constructed message body to the base station.
- the message body can shorten the terminal access time, improve the terminal access speed and access channel utilization, increase the system access capacity, and help reduce the collision probability of access messages.
- 1 is a structural diagram of an access slot provided by the prior art;
- FIG. 2 is a method for accessing a terminal according to an embodiment of the present invention;
- FIG. 3 is a structure of a terminal according to an embodiment of the present invention;
- the embodiment of the present invention constructs an access message body by calculating the length of the access message body of the access message in real time, and replaces the length of the uniformly configured access message body with the calculated length of the access message body, and sends the constructed message body to the base station.
- An embodiment of the present invention provides a method for accessing a terminal. As shown in FIG. 2, the method includes:
- the length of the access message body of the access message may be calculated according to the length of the content of the access message body of the access message. For example, if the content of the access message body of the access message includes 500 bits of user data and 38 bits of other overhead, the length of the content of the access message body is 538 bits, and the length of each frame corresponding to a certain transmission rate is 192 bits. At this time, the value of the access message body is rounded up to 538/192, and the final result is 3.
- the access time slot is configured according to the length of the configured access message prefix and the length of the access message body.
- the length of the configured access message prefix is the access message obtained from the air interface message sent by the base station.
- the length of the incoming message prefix is replaced by the length of the configured access message body; the first sum value of the access message body length and 3 is calculated; the length of the configured access message prefix is calculated to be the second of 1 And the value; the first and the value and the second sum value construct the access slot.
- the calculated access message body length is less than or equal to the configured access message body length. It should be noted that, in practical applications, the calculated access message body length may also be greater than the configured access message body length.
- the start time point of the terminal accessing the CDMA system is a boundary point of the access time slot, that is, the access start time point is an integer multiple of the access time slot.
- the access slot alignment time is a random value between 0ms and (( 1 + PAM SZ ) + ( 3 + MAX CAP SZ ) ) x 20ms. In practical applications, the access slot alignment time is generally averaged. , that is, the average time of the access slot alignment is one-half of the access slot alignment time, that is, (( 1 + PAM SZ ) + ( 3 + MAX CAP SZ ) ) x 10ms.
- the value of the parameter MAX_CAP_SZ is 7 and the value of the parameter PAM_SZ is 3.
- the value of the parameter MAX_CAP_SZ and the value of the parameter PAM_SZ are obtained by the terminal from the air interface message sent by the base station.
- the current access message is the access message L.
- the parameter MAX_CAP_SZ value and the parameter PAM SZ value are only used to describe the embodiment, and the scope of protection of the present invention is not limited to this value.
- the length of the access message body of the access message L is calculated to be 6 according to the length of the content of the access message body of the access message L.
- the content of the access message body of the access message L includes 1000 bits of user data and 76 bits of other overhead, and each frame length corresponding to a certain transmission rate is 192 bits.
- the access message body is The value of length 1076/192 is rounded and the final result is 6.
- the length of the access message body of the access message L is only for describing the embodiment, and the scope of protection of the present invention is not limited to the value.
- the parameter PAM_SZ value is summed with 1 to obtain a second sum value of 4 (frame); the length value 9 of the constructed access message body is summed with the second sum value 4, and the access time slot is obtained as 13.
- the terminal sends an access message prefix to the base station.
- the access slot alignment time is half of the product value of 13 and 20 ms, that is, 130 ms.
- the terminal sends the constructed access message body to the base station according to the calculated length of the access message body.
- Table 1 is a table of the relationship between the configured parameter MAX_CAP_SZ and the terminal access time. Table 1
- the parameter PAM SZ is m, which takes a value of 3
- the parameter MAX CAP SZ is n, which takes a value of 7.
- the time of the terminal accessing the system includes two parts, one is the access time slot. The length of time; the second is the average time length of the access slot alignment.
- the terminal access time is 420ms.
- the length of the access message body of the calculated access message is 6.
- the terminal access time is shortened by 30ms.
- the terminal access time is shortened by 180 ms. It can be understood by those skilled in the art that if the configured parameter MAX_CAP_SZ minus the calculated length of the access message body is equal to K, the terminal access time can be shortened by (30*K) ms, where K is an integer.
